Antennas Serve P25 Applications From 132 To 174 MHz

A pair of wideband mobile load coil antennas is well suited for Project 25 initiative applications, which promise to enable federal, state, and local public-safety agencies to communicate with other agencies and response teams during emergencies. The B1322W covers a field-tunable frequency range of 132 to 174 MHz. This antenna allows the user to obtain a VSWR below 2.0:1 at a desired center frequency. Its sibling, the B1360W, does not require tuning. It spans 136 to 174 MHz with a maximum VSWR of 2.0:1. Both antennas have an omnidirectional pattern with vertical polarization. They handle maximum input power of 100 W. The antennas include one-piece solid brass inserts, durable ABS injection-molded housings, and weather-tight bases with built-in 0-rings. Gold push-pin contacts preserve power transfer over time while the stainless-steel whips resist bending and rust.
